test-image.sh publishes the plugin on the host, bakes it into a stock
jellyfin/jellyfin image via Dockerfile.test, and runs it on :8096, with
optional egress through a LAN gateway (DOCKER_GATEWAY, e.g. the Swiss
VPN box) for geo-blocked streams.
JELLYFIN_TAG (default 12) selects the image and the matching plugin
build: 10.9/10.10 -> net8.0, 10.11 -> net9.0, 12 -> net10.0, with the
generated meta.json targetAbi to match. Images are tagged per version
(srfplay-test:<tag>) so several can coexist.
